Vanderhall Motor Works

Vanderhall Motor Works is a privately held American vehicle manufacturer founded in 2010 by Steve Hall and headquartered in Provo, Utah. The company hand-builds three-wheeled autocycles — the Laguna, Venice, Venice Speedster, Carmel and Santarosa — alongside the all-electric Edison and the quad-motor Brawley off-road UTV, selling through an independent dealer network rather than direct to consumers. Its software footprint is internal rather than commercial: Vanderhall runs a dealer portal, an admin portal and a parts/accessory shop on its own domain, and the admin portal publishes an OAuth-protected Model Context Protocol (MCP) endpoint at https://portal.vanderhallusa.com/mcp with RFC 8414 authorization-server metadata, RFC 9728 protected-resource metadata and RFC 7591 dynamic client registration. There is no public developer program, no published OpenAPI, and no public API reference.

Vanderhall Motor Works publishes 1 API on the APIs.io network. Tagged areas include Company, Automotive, Manufacturing, Electric Vehicles, and Powersports.

Vanderhall Motor Works’ developer surface includes support, authentication, and 16 more developer resources.
